A Priori Reliability of Electrical Machines and Its Verification by Testing

Year: 2026

Type: conference-paper

Abstract: A method is proposed for determining the reliability of electrical machines of the most widely used types during their design stage and for verifying this reliability through testing of the components intended for them. The method is invariant with respect to the type of machine and its operating mode. Particular attention is given to its practical application in real engineering practice. The method is applicable to both direct current and alternating current machines, with or without a commutator, operating in either generator or motor mode. It is based on the evaluation of the probability of failure-free operation over a specified time interval, determined on the basis of the reliability characteristics of their windings, bearings, and commutation system.
